My friends came to my home and played my 3DS, and i told them to be careful not to make any scratch or smudge, but they left some fingernail mark on my slide pad which is very ugly and I cant stop visualizing it, I mean it is distracting me, god I cant stand it anymore, so I want to ask how do I remove them? thank you.

My 14 year old brother did this to mine also, he also tried pushing the start button below the screen with the stylus because he was to lazy to set it down and push it with his thumb, so now there is an indent on the start button too. Pissed me off.

I somehow got a nail print on my old 3DS, and it really annoyed me. But that was nothing. A couple months afterward the entire rubber coating began to come off all around the edges until I couldn't stand it anymore and just took the rest off myself, leaving only a little piece on the right side for my left thumb grip with. It actually works quite well, though it is not a pretty sight.

oh sheee.. seems that theres no rubber part of the analog stick replacement, just the lower part of it, so if I send it to Nintendo, there will be rubber part for fix? is there any Nintendo "shop" in hong kong? I am living in Hong Kong anyways
